In the type of filtering apparatus described in Specification 1,026,803 (i.e. having a plurality of parallel filter units 15 selectively connectable to a reflux port 9 to backwash them), a reflux pipe 36 is connected to a device (e.g. 37-41) for automatically throttling the reflux liquid flow after a predetermined volume has flowed through the reflux port 9. As described, when aperture 14 is put into communication with port 9 by valve member 23, 35, backwash liquid rushes into surge chamber 37, rapidly filling it; thereafter it must pass through orifice 40, thereby throttling the flow; optionally, orifice 40 is adjusted so that subsequent to the initial rush the pressure at outlet 7 remains constant, see curve a-b-f, Fig. 3 (not shown).

Patent GB-561866-A (GB)
Abstract: 561,866. Current meters. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and KLEPP, E. C. Nov. 2, 1942, No. 15415. [Class 37] In a moving-coil instrument of the kind comprising two concentrically-arranged coils mounted to rotate in the same magnetic field and wound to produce opposing torques, the air gap is of constant width along the path of movement of the coils and the cross-section of the core or of the magnet pole is such that a part of the core or the magnet pole facing the gap approaches saturation, so that the field strength in the gap decreases along the path of movement away from this part. The core or the magnet poles or both may be formed from a metal alloy, the permeability of which varies in accordance with a predetermined law so as to be high at low flux densities and low at high flux densities. In the construction shown in Fig. 1, a core 12, in the form of a cylindrical annulus, is mounted coaxially with the pole faces 11 of a magnet 10 so as to provide a gap 13 of constant width. Encircling the core are two coils 14, 15 wound on a former 16 mounted to rotate about an axis coaxial with the core. The coils cross one another over the ends of the core and intersect on the axis. The cross-section of the core is such that the flux flowing through it from the magnet pole faces causes saturation at diametrically opposite points so that the flux in the air gap is graded from a maximum near the outer pole edges to a minimum at the centre of the poles. In a modification, Fig. 2, the core 18 comprises a gapped annulus and is in direct contact with one pole 19 of a horseshoe magnet 20. The other end of the magnet is either provided with a continuation or abuts against a disc-shaped polepiece 21 so that a gap 22 of constant width is formed. Two coils 23, 24 pass through the centre of the core 18 across the two flat faces and axially across the periphery. The cross-sectional area of the core or the polepiece 21 or both is chosen so that saturation takes place adjacent to the magnet proper and the flux density diminishes along the path of movement. Specifications 546,468 and 556,915 are referred to.

A pilot actuated valve for controlling flow in a steam line is totally enclosed within a section 2 of the line. The valve has a main closure member 5 moved by a piston 6 when pilot valve 9 is opened by pressure supplied to its actuating chamber 22B thereby permitting upstream pressure in chamber 15A to be vented through chamber 15B and conduit 31-33. The arrangement being such that the degree of movement of closure member 5 is proportional to the pressure applied to chamber 22B through control inlet 29. Fig. 2 (not shown) illustrates a modification in which the pilot valve seats in the main closure member. The valve may be used to control admission of steam to a turbine by operating a control valve Fig. 3 (not shown) feeding in inlet 29 in accordance with a signal derived by comparing a speed responsive signal with a signal dependent on the position of the main closure member.

The lid of a storage battery has a longitudinal channel 12 communicating with each cell by a filling tube 13 extending to just below the desired electrolyte level, closed by a cover 16 having a longitudinal part 19 in a longitudinal groove 14 in the lid, part 19 having a series of grooves 21 such that they connect with vents 15 in the base of the groove when the cover is closed while part 19 closes the vents when the cover is open. Thus after filling or topping up the battery to the top of the filling tubes closing the cover opens the vents and equalizes the liquid level inside and outside the filling tubes. As shown in Fig. 3 longitudinal movement of the cover 16 is prevented by walls 23 which engage with slots 22 in hinge pin 19. In another embodiment (Fig. 4, not shown) the cover opens through 180 degrees and in both the fully open and the fully closed positions slots 24 in the cover are engaged by portions 25 of the walls of the groove 14.

A scraper blade 8 is pivotally suspended from a travelling gantry 5 by arm(s) 7 and is raised or lowered by a motor 15 which may rest on the gantry but can be lifted therefrom so that its weight serves to urge blade 8 downwards. In Fig. 1, electric motor 15 operates an extendable arm 12, 13, 14, which may be oil-filled and is pivoted at 11 to arm 7. A lever 18 is pivoted to the gantry at 19 and carries the motor, universally pivoted thereto, and an axially movable weight 21. The motor is controlled by a switch 25, actuated by a stop 24 on lever 18, so that after blade 8 has engaged the bottom 1 of the settling tank the motor continues to. turn, lifting lever 18 so that the weight 21 and the weight of the motor act through arm 12 ... 14 on the blade. Alternatively, the motor is controlled by switch 26 and adjustable contact 27, whereby the blade is simply lowered to a preselected position, in which lever 18 rests on its stop 22, and only when the blade meets resistance is lever 18 raised to exert weight thereon. Switch 25 may be located in the place of. stop 22. In Fig. 2 (not shown), the extendable arm 12, 14 is vertical and the motor 15 is raised vertically in roller bearings so that its weight acts on blade 8. In both embodiments, when the blade 8 is being raised the motor (and weight) are supported by the gantry. Extendable arm 12, 14 may employ a rotating screw and captive nut or a rack and pinion. Blade 8 sweeps solids into a sump.

The two discs are urged towards each other by hydraulic cylinders 64 and 66, the disc 44 having a central stem which passes through the gear and co-operates with a recess in the disc 46 (Fig. 3, not shown). Each disc is acted on by two backing rollers 86 and 84 or 90 and 88 (Fig. 4), the rollers being mounted on a support 98. To position a gear W ready for rolling, the  support 98 is lowered by a ram 21, and is then shifted laterally by a toggle lever 110. The gear is positioned between the discs and is supported by the backing rollers.
